Cylinder liner for Cummins 6CT

The cylinder liner, part number 3919937, acts as the internal sleeve for the engine block in the Cummins 6CT diesel engine. It creates the cylinder wall where the piston travels, isolating the engine block from the heat and friction generated during the combustion cycle. This component is engineered to maintain the structural integrity of the cylinder bore while facilitating heat transfer to the cooling system. Proper installation ensures the required clearance for the piston and rings, which is necessary for maintaining engine compression and oil control.

This component is compatible with the Cummins 6CT engine series. It is manufactured to meet the original technical specifications required for this engine model. The liner serves as a replaceable wear surface that protects the main engine block from the direct mechanical stress of piston movement and the thermal loads of the combustion process. By providing a consistent bore diameter, the liner supports efficient operation of the piston assembly and helps maintain the overall performance parameters of the engine system.
